Title: Microjoint separator
Inventor: TAJIMA KOICHIRO
IPC: B26F1/38
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To reduce punching load by providing a necking part in a joint part shape of a work for a microjoint processing in the case of punching of the outside of the joint part so as to prevent a part from entering into under a waste material after separation of parts. SOLUTION: Positioning is performed in a punching position 26 in the outside of a joint part 4 of a work 1. This constitution reduces possibility that a processing part 2 enters into under a waste material in punching. After completing of the positioning, a microjoint is separated by punching of a punching head. Then, the microjoint processing part is so processed as to have a necking part 29. Therefore, deformation of the material concentrates at the necking part 29 in punching so that the microjoint is separated only applying load on the punching position 26 by a punching head. The punching load can be thus reduced.

Title: Voltage control circuit for fuel cell
Inventor: YAMAZAKI YOSHIFUMI
IPC: H01M8/04
Filed: 1986-10-15
Abstract: PURPOSE:To quickly discharge the potential in a no-load mode by using plural discharge resistance or a discharge resistance having plural taps to discharge the no-load potential of a fuel cell. CONSTITUTION:The output potential of a fuel cell 1 is kept within a no-load high potential area immediately after discontinuation of operation of the cell 1. Thus, a high potential deciding means 6 works first and an open/close switch controller 8 decides the open/close states of switches 1s-ns of a discharge resistance open/close switch 4. Then, a close command is sent to one of the open switches through an open/close switch open/close command 9. As a result, one of switches 1s-ns is closed and one of discharge resistances 3 functions to reduce slightly the no-load high potential. Thus, some of resistance 3 are connected to an output circuit of the cell 1 and a low potential deciding device 7 works when the potential of the cell 1 is reduced less than a certain control potential level after a prescribed period of time. Then, the resistances 3 are gradually separated from the cell 1.

Abstract: PURPOSE:To obtain electronic parts which are free from sagging of coating materials by coating the lead-wire part of the electronic parts with a water- repellant material after the element of the parts is coated with an under coat of a powdery resin and, then, coating the element with a finish coat of the powdery resin. CONSTITUTION:When an element 1 is pulled out of resin powder 11 in the powdery resin tank of a coating machine a fluid dipping process, etc., after the element 1 is preheated to 100-200 deg.C and dipped in the powder 11, the powder 11 melts due to the heat of the element 1 and the element 1 is coated with an under coat 13. Then a coat 14 of a water-repellant material 16 is formed on lead wires 3 coated with the under coat 13. A fluorocarbon or silicon resin is used as the water-repellant material 16. The element 1 is again preheated to 100-200 deg.C and dipped in the resin powder 11 in the tank. When the element 1 is pulled out of the powder 11, the resin powder melts due to the heat of the element 1 and a finish coat 17 is formed of the resin powder. This coat 17 does not cover the lead wires 3, since the resin power is repelled by the coat 14 of the water-repellant material. As a result, electronic parts which are free from sagged paint are obtained.
